# USAGE : ./install [<perl script name> | AUTO <dir> <tmp_dir> <perl_dir> [<install_location>] ]
# USAGE : by default all scripts will be installed
#
# REQUIREMENTS : /bin/bash and sed
#
# This script will :
# - Check perl binary (and asks for path)
# - Ask for nagios plugin path and checks for file "utils.pm" in it (default /usr/local/nagios/libexec)
# - Ask for temporary file location (default /tmp)
# - Check Net::SNMP version
# - Install plugins in the plugins directory and modify paths if necessary.
